The Jam Heavy Metal HX-P920 is a small, metallic speaker that gained its top-of-the-shop rating thanks to its impressive bass power, its ability to fill a room and the surprising clarity of its midrange.

Carrying it about is simple too - the build is smooth, the metal is sleek, and it's got good balance to its weight. It feels reassuring yet convenient.

With a claimed battery life of eight hours, a 3.5mm input and 20W of stereo power to be getting on with, those looking for a straightforward wireless speaker shouldn't hang around.
